Hundreds Of New Viruses With Enormous Genomes Blur The Boundaries Of Life
Defining life is hard. Plants, animals, and amoebas certainly fit, but what about viruses or prions? For those who put viruses on the non-living side of that division, things just got a bit awkward with the discovery of hundreds of viruses whose genome resembles bacteria. Bacteriophages are bacteria-infecting viruses. Some have been used in place of antibiotics, but their diversity is so great we’ve barely scratched the surface. Now, a study published in Nature has turned up 351 bacteriophage species with genomes at least four times as large as most members of their class, almost four…
